Plain weave and square hole mesh
Plain weave and square-hole polyester mesh are the simplest open structures we produce, and among the most widely used across screening, filtration, drying and conveying duties. Hengfeng manufactures this family in-house. Because a plain weave is defined by mesh count, yarn diameter and open area, the specification is derived directly from the separation or support task. We confirm those three parameters together with the width, joining method and operating environment before issuing a written specification.
Typical uses
Applications include screening and sizing, drying and conveying belts, filtration support, and general industrial separation. A coarse, heavy-yarn mesh carries load and resists abrasion; a fine mesh retains smaller particles but reduces open area and throughput. These are trade-offs, not quality grades, and they are set against the actual duty.
What is specified
Mesh count, yarn diameter, open area, fabric thickness, material and finished width are agreed together. Where the mesh runs over rollers or is cleaned under pressure, dimensional stability and edge treatment are reviewed with the same care as permeability. Anti-static, temperature and chemical requirements are recorded as conditions on the specification.
Why we do not list fixed values here
A mesh count without its yarn diameter and test condition is not a usable specification, and publishing a generic table would invite incorrect substitution. Instead we issue the numeric values in a written proposal tied to your application, along with the test method used to verify them.
Configurable dimensions
- Mesh count in warp and weft directions
- Monofilament material and yarn diameter
- Open area and thickness
- Finished width, length and edge treatment
- Joining or endless arrangement
- Temperature, chemical and anti-static requirements
- Surface finish for product release or support
Information to send for a configuration review

- Cleaning method, pressure and blinding problems
Industry reference specifications (public sources) — not Hengfeng measurements
These are publicly published, industry-common reference values transcribed from third-party supplier and competitor pages on 9 November 2026, with the source and test conditions shown beside each table. They are NOT Hengfeng test results, NOT a Hengfeng product specification, and NOT a performance or supply commitment. They exist so that a technical discussion can start from comparable terms. Final values are confirmed in a written specification against your machine conditions.
Polyester plain / square-hole mesh examples
Square-hole mesh is specified by filament diameter, density, mesh count, aperture and air permeability. Multiple test conditions are often printed in the same table, so the condition column must be read with the value.
| Code | Filament Ø warp / weft (mm) | Density warp / weft (roots/cm) | Weight (kg/m²) | Thickness (mm) | Aperture warp / weft (mm) | Air permeability (m³/m²·h) | CFM @127 Pa | Open area (%) |
|---|---|---|---|---|---|---|---|---|
| 021002 | 1.0 / 1.0 | 2.85 / 2.65 | 0.60 | 1.85 | 2.50 / 2.77 | 32000 | 2000 | 52.55 |
| 031002 | 1.0 / 1.0 | 3.2 / 3.25 | 0.80 | 1.86 | 2.12 / 2.07 | 25600 | 1600 | 45.9 |

Test conditions & comparability
The source prints an m³/m²·h column, a CFM @127 Pa column and a separate L/m²/s @200 Pa column. A Chinese reprint of a similar table labels the 200 Pa l/m²/s figure (e.g. 12600 for 021002) simply as "air permeability" — a unit/condition mix-up. This site keeps the original column separation and performs no conversion.
- Four joint types are listed by another supplier for the same family: stainless-steel clipper, endless, spiral ring and pin ring.

Air-permeability values are comparable only when the unit, differential pressure and test method match. The tables above come from different sources, some without a stated test condition, and cannot be used as acceptance criteria or a performance promise. Binding values are those in the mutually confirmed written specification.
Frequently asked questions
Can I order by mesh count alone?
We do not recommend it. Mesh count must be paired with yarn diameter, open area and the test method. We confirm all of them in a written proposal.
Is this family made in-house?
Yes, on Hengfeng’s own monofilament, weaving, heat-setting, seaming and inspection lines.
Do you supply endless or joined belts?
Both are reviewed. The choice depends on roller geometry, installation access and whether local repair is needed.
Hengfeng manufactures this family in-house. The parameter tables on this page are publicly published, industry-common reference values transcribed from third-party supplier and competitor pages, with each source and test condition shown next to the table. They are NOT Hengfeng measurements, NOT a Hengfeng product specification and NOT a performance or supply commitment. Model designations, permeability, dimensions and seam details are configured against your machine conditions and become binding only in a written specification. Request a configuration review for that specification.
